The fact is, the guy is an incompetent f***. I use my turn signals EVERY time I chage lanes or make a turn, and NOBODY boxes me out. I don't give them the opportunity.
First of all, I pick a suitably sized gap into which to merge. This means I'm far enough ahead of the other vehicles in the target lane that I can merge in without interference. After selecting a proper merge gap, and when my turn signal goes on, I don't sit there like some mope waiting for five minutes before I begin my lane change - I begin my lane change *immediately*. Thus, even if somebody wanted to speed up and block my lane change, by the time they realize what's happening and catch up to my position I'm already in the new lane. Also, unlike the dumbpoos who SLOW DOWN when they want to change lanes, royally f***ing over everyone around them, I SPEED UP (if necessary) or, at the very least, maintain speed while I change. I see no need to annoy the drivers behind me by making them slow down just because I want to change lanes.
If you change lanes correctly, it's virtually impossible for even the most territorial jerkweed driver to block your maneuvers. OTOH, the people who have problems have yet to master this basic skill.
